Abstract
The invention discloses a once mounting, locating and constructing method for a steel ladder outside a concrete silo following sliding mould construction. A construction process comprises the following steps of: leaving an upper inlet on a sliding mould operating platform of the concrete silo and fixing an upper end of a prepared tool type pulling steel ladder on a sliding mould enclosed ring; after sliding the sliding mould operating platform to a preset height during a concrete silo construction process, welding an engineering steel ladder on an outer wall of the concrete silo; and then hanging and welding the tool type pulling steel ladder on the engineering steel ladder; and repeating the steps till completely constructing. According to the method provided by the invention, rental fee of materials about ** Yuan can be saved, the cost of purchasing a safety net foot plank about ** Yuan can be saved, the cost of assembling and disassembling a riding track tower about ** Yuan can be saved, the cost of materials about ** Yuan can be saved, the cost of disassembling a needed machine matched with a tower crane or truck crane about ** Yuan per day can be saved, and the cost of a mounting machine of the steel ladder about ** Yuan can be saved. Totally, the cost about ** Yuan can be saved, a construction period can be reduced by two days, and the method is practical and economical as well as safe and has remarkable composite economic benefits.
Description
Technical field
The present invention relates in the civil engineering work the outer steel ladder construction method of installation of people on the concrete silo.
Background technology
It is work items common in the industrial construction that the outer cat ladder of concrete silo is installed, in the construction, for the constructor easy for going up and down; All are construction technologies of setting up people's packway in the interim special use along the silo outer wall at present; First construction concrete silo main body, when the silo main body construction behind certain altitude, outside the silo main body, set up interim on people's runway support body; Support body raises with the growth of cylindrical shell construction height; Construct after design elevation binds at cylindrical shell, remove interim people's runway support body of going up of setting up again, installs nonvolatil on people's steel ladder.Concrete silo construction with raw material silo is an example, need rent and set up support body ton surplus steel pipe 100, and wide scaffold floor 140 linear meters of 20cm, security maintenance is with 630 square metres on net.Construction finishes and remove to go up people's runway and use support body, utilizes tower crane installing engineering steel ladder again.This job practices takies the construction period separately, and outrigger is set up the waste that causes manual work, shelf pipe etc., and efficiency of construction is low.
Summary of the invention
Be the reduction of erection time, saving equipment, we rent tools takes and labour cost, reduces entreprise cost, and the present invention provides the outer steel ladder of a kind of concrete silo with the disposable installation in position job practices of slding form operation.
Work progress of the present invention and principle are:
When more than the concrete silo engineering construction to 2.5 meter, first step engineering steel ladder is installed, then utilize the silo sliding-mode platform, settle helper on the pull tool-type, articulate mutually with the engineering steel ladder, thereby can no longer set up interim construction and use people's packway.
Work progress of the present invention may further comprise the steps:
A, the tool-type pull steel ladder made upper end is fixed in the sliding formwork enclosure;
B, the lower end with tool-type pull steel ladder articulates the engineering steel ladder then;
C, after the sliding-mode platform cunning is raised to setting height in the concrete silo construction, again the engineering steel ladder is welded on the silo outer wall;
D, repeat above b～c step, finish until construction.
The technological progress that the present invention obtains:
In the tradition silo slip form construction; It generally is after sliding formwork finishes that steel ladder is installed; Rental car is lifted up into capable steel ladder and the lifting of steel ladder platform, and the silo engineering is generally highly bigger, generally highly all more than 40 meters; That have even reach more than 70 meter, this mobile crane that just requires steel ladder is installed must use large-scale mobile crane could guarantee hoisting height.And adopt job practices of the present invention; When slding form operation, promote the installation steel ladder, the back steel ladder is installed is can be used as personnel's passage of operating platform up and down, can practice thrift the expense of setting up people's packway and installation steel ladder like this with sliding formwork; Reduced the turnover we rent tools the expense and tower crane equipment leasing expense; Reduce administrative staff's management fee, also can shorten the construction period greatly simultaneously, reduce construction safety risk.
The present invention is an example with clinker warehouse construction in the gold circle cement grinding production line of Qinghai, can save 1300 yuan of packway material rental charge, steel tube fastener rental charge totals, can save 9500 yuan of safety net scaffold floor buying expenseses, can save packway and set up 16000 yuan of demolition costs; Can save 10800 yuan of cost of materials; The machinery that can save dismounting needs tower crane or mobile crane to cooperate takes 800 yuan/day, can save steel ladder 7000 yuan of machinery expenses are installed.Promptly adopt the present invention to promote with sliding formwork steel ladder technology is installed, total can be reduced expenses 3.38 ten thousand yuan, and can shorten 2 day construction period, and collection is practical, economical, safety is one, has significant overall economic efficiency.
Description of drawings
Fig. 1 is engineering steel ladder of the present invention and tool-type pull steel ladder syndeton sketch map.
The specific embodiment
As shown in Figure 1, the outer steel ladder of concrete silo of the present invention comprises following construction sequence with the disposable installation in position job practices of slding form operation:
A, keeping somewhere population on the concrete silo sliding-mode platform, the upper end of the tool-type pull steel ladder of making 2 is being fixed in the sliding formwork enclosure;
B, the lower end with tool-type pull steel ladder 2 articulates on the cushion cap 3 on engineering steel ladder 1 top then;
C, after the sliding-mode platform cunning is raised to setting height in the concrete silo construction, (retrieving tool formula pull steel ladder mobile ladder) is welded on engineering steel ladder 1 on the silo outer wall;
D, repeat above b～c step, finish until construction.
Claims (1)
1. the outer steel ladder of concrete silo is characterized in that may further comprise the steps with the disposable installation in position job practices of slding form operation:
A, the tool-type pull steel ladder made upper end is fixed in the sliding formwork enclosure;
B, the lower end with tool-type pull steel ladder articulates the engineering steel ladder then;
C, after the sliding-mode platform cunning is raised to setting height in the concrete silo construction, again the engineering steel ladder is welded on the silo outer wall;
D, repeat above b～c step, finish until construction.
